Sebring 2010 2.7 v6 137kw misfire problem
 

Hi.
So here is the problem.
I start the car with cold engine and everything is OK.
But when it cools (for example I go to shop and come back), after that it has one cylinder missing. If engine cools way down (for example it stays over night) then all is OK.
I have an OBD reader and it says P0203 Injector 3-circuit malfunction.
So I'm guessing the problem is with injector 3
My question is what is the cilynder order for my engine(Can't find it in the internet). And is the problem with injector or wiring?
Thanks for the help
